Abstract

Each user who interacts with the Internet and information technology can provide feedback on the specific application. One of the applications which were used as social media is youtube. Various comments are given so that it becomes a challenge for the organizers. In this study, the concept of data mining was needed through the K-Nearest Neighbor method as a tool for classifying in addition to investigating comments that have the potential to be sentimental. There are three factors that are observed as input data, namely Services Quality, Information Quality, and Responsibility when the dataset is collected from social media applications. The initial phase of analysis is to extract the datasets from youtube then carried out pre-processing to the analysis phase. As the result shows that the method which was proposed is able to describe the accuracy rate of up to 88% through the confusion matrix technique. Therefore, the performance of K-Nearest Neighbor has provided a classification with positive and negative sentiment analysis classes.

Abstract

Today, many applications or technologies have been produced by every software developer. However, the success of all there is the decision of each user. Users have two possibilities to accept or reject a technology that is presented. The TAM model has been widely researched and undergone development and changes besides being quite reliable in predicting the level of technology acceptance in all countries in the world. In this study, we will recapitulate all studies on the acceptance of technology in the field of Education that handles online learning. The results showed that there was 51 article review publication were selected through some process of review. The period taken ranges from 2011 to 2020. The main findings show that there are differences in the models, methods, and applications identified. Since the TAM model has two basic variables, namely perceived ease of use and perceived usefulness as a framework for analyzing the make and influence technology acceptance. In this study also provides information about the results of the identification of some of the gaps in current research and also in the future. Therefore, the results of a systematic literature review were able to provide a better understanding of TAM especially in the perspective of education in online learning.

Abstract

Many companies lack configuration systems due to the need to protect assets from unauthorized access by individuals or groups. Data mining can help by securing the configuration system to identify accounts in the database. Given the sensitivity of activities on the database system, access permissions are a major concern, especially with unauthorized users. Excessive permissions can compromise database security, making it important to group users into authorized and unauthorized classes. This study uses the decision tree method to extract and investigate factors that affect excessive permissions, and validates the dataset with 10-fold cross-validation to ensure data quality. The final result identifies two classes for user access, showing that the decision tree method performs well with significant values on the AUC curve and the Confusion Matrix

Abstract

The level of digital readiness within Islamic Higher Education Institutions (IHEIs) has emerged as a critical concern, drawing increasing scholarly and institutional attention over the past five years. This study aims to examine the empirical relationship between two key dimensions: digital readiness, as reflected by the National Readiness Index (NRI), and progress toward the Sustainable Development Goals (SDGs). Data were collected from more than 20 IHEIs between 2023 and 2024 to support a sequential analytical approach. Pearson’s correlation coefficient was employed to identify associations between NRI-based digital readiness and SDG performance within the IHEI context. Subsequently, cluster analysis was conducted using the Duda–Hart Index, while the Pseudo T² statistic was applied to validate the robustness of the clustering outcomes. A cartographic visualization was also generated to illustrate variations across readiness and sustainability clusters. The results indicate a considerable disparity between digital readiness and sustainability among IHEIs. Only a limited number of institutions demonstrate consistent performance in both areas, suggesting that effective leadership and strategic investment in digital infrastructure are essential prerequisites for achieving sustainable institutional transformation.

Abstract

The rapid advancement of digital technology requires religious educational institutions to adapt to changes in service delivery, including counseling practices. In Islamic boarding schools (pesantren), counseling activities are still predominantly conducted through conventional approaches and have not fully utilized the potential of digital media. Based on this condition, this community service program aims to promote the digital transformation of counseling practices through the utilization of virtual platforms using the Participatory Action Research (PAR) approach. The program was implemented at Pondok Pesantren An-Nida, Cirebon City, through three main stages: observation, implementation, and participatory reflection. The observation stage was used to identify digital readiness and institutional needs, the implementation stage involved digital literacy training and virtual counseling simulations, and the reflection stage evaluated program effectiveness. The results indicate improved understanding, empathic communication skills, and awareness of digital ethics and privacy. The participatory approach proved effective in strengthening institutional collaboration and developing an adaptive cyber culture. This program demonstrates that digital transformation within Islamic boarding schools can harmoniously align with religious and ethical values when developed through collaborative, reflective, and sustainable processes.
